Abstract

The article by Lozano-Fernández et al. (2015) revises the chronological range and paleoenvironmental inferences for unit EVT7 at Vallparadís, based on a micromammal sample slightly larger than the original one published in Martínez et al. (2014). However, in this new chronological and paleoenvironmental interpretation, the virtually identical results (0.95–0.98 Myr and predominant humid landscape) for the site published in Martínez et al. (2014) are omitted. Furthermore, they claim an age of ca. 1.2 Myr for unit EVT7 at Vallparadís, attributing this chronology to the archaeological team who excavated the site. However, this proposal is not in accordance with the date close to the upper boundary of the Jaramillo subchron (ca. 0.9 Myr), which this team has defended in their articles. Thus, the results and conclusions presented by Lozano-Fernández et al. (2015) do not revise previous studies, but rather confirm the interpretations drawn from the sample analyzed by Martínez et al. (2014). [ABSTRACT FROM AUTHOR]

Abstract

Vallparadís is one of the best calibrated and most accurately dated archaeological sites from the European Early Pleistocene. Chronological analyses combined with palaeomagnetism, ESR-U/series and OSL, and the biochronology of macro- and micromammals are fully consistent and situate the site just above the upper limit of the Jaramillo subchron. In this article we compare the mandibular first molar (m1) of individual adult specimens of Mimomys savini recovered from level 10 (EVT7) at Vallparadís with specimens from the stratigraphic sequence at Gran Dolina (Atapuerca), Fuente Nueva 3 and Barranco León D (Orce). This comparison allows us to chronostratigraphically relate level 10 at Vallparadís with level TD5 at Gran Dolina and to fix the former's chronology to around 0.98–0.95 Ma (MIS 27) and, therefore, prior to level TD6 in which fossil remains of Homo antecessor were recovered. The chronology of Vallparadís and the set of contemporary palaeoclimatic proxies regarding the Iberian Peninsula strengthen the hypothesis that hominins continuously populated Europe, at least in Iberia, throughout the late Early Pleistocene between the Jaramillo subchron and the Matuyama–Brunhes boundary by overcoming the climatic fluctuations and changes to the landscape that occurred during this period.

Abstract

The occurrence of the genus Iberomys is testified in Italy and the Iberian Peninsula from the Early Pleistocene on. The genus comprises two extinct voles: I. huescarensis from the Early Pleistocene to the early Middle Pleistocene and I. brecciensis (=mediterraneus) from the Middle to the early Late Pleistocene. I. cabrerae, has been present in Spain from the early Late Pleistocene, enduring right through to today. The fossil record of Iberomys in Italy is poor in comparison with those in the Iberian Peninsula and southern France. I. huescarensis has been identified in Italy at the Rifreddo and Spessa sites, while I. brecciensis has been recognized at Zoppega 2, Montagnola Senese II, Isernia, Valdemino, Polledrara di Cecanibbio and Paglicci. A revision of the specimens of the genus Iberomys in Italy and a comparison with the fossil records of southern France and the Iberian Peninsula show that the origin of the Early Pleistocene species (I. huescarensis) is clearly in the Iberian Peninsula, where the species having evolved from ancient populations of Allophaiomys nutiensis. The origin of the species I. brecciensis is still unknown. It seems to appear at the same time in Italy and in the Iberian Peninsula, and its extinction occurred during the late Middle Pleistocene-early Late Pleistocene in Italy, France and Iberia simultaneously.

4. Precisiones sobre la sistemática de Iberomys Chaline, 1972 (Arvicolidae, Rodentia, Mammalia) del Pleistoceno inferior de la Sierra de Atapuerca (Burgos, España)

Subjects
Iberomys huescarensis, Atapuerca, Trinchera Dolina, Iberomys brecciensis, Lower Pleistocene
Abstract

The Iberomys lineage is represented by the species I. huescarensis (Ruiz Bustos, 1988), at the lower levels (TD3 to lower TD8) of Trinchera Dolina (Sierra de Atapuerca, Burgos), and not by I. brecciensis Ciebel, 1847 as stated previously. Both species mainly differ in the communication of triangles T4 and T5 of the first lower molar dental pattern, broad in I. huescarensis and narrow in I. brecciensis. I. huescarensis is the ancestral species of the I. brecciensis-cabrerae lineage, and characterizes the late Lower Pleistocene and the transition Lower-Middle Pleistocene in the Iberian Peninsula
